Abstract

The compressed gas canister includes an ejection valve (16) having a bearing surface (26) that does not protrude beyond the edge of a bowl when the valve is in the rest position. The bearing surface is set back from the surface facing towards the outside of a seal (23) when the ejection valve is in the gas ejection position.

Description

L'invention concerne tout d'abord une cartouche de gaz comprimé destinée à alimenter en gaz un appareil de fixation à gaz comprimé, c'est-à-dire un appareil d'entrainement d'éléments de fixation du type clou, comportant un dispositif d'admission. Le dispositif d'admission de l'appareil est généralement une électrovanne.The invention firstly relates to a compressed gas cartridge for supplying gas to a compressed gas fixation apparatus, that is to say a nail-type fastener driving apparatus, comprising a device intake. The device of admission of the apparatus is generally a solenoid valve.

Les dispositifs d'admission connus, comme par exemple celui décrit dans FR 2 771 796 , comportent un embout d'admission mâle, à l'intérieur d'une cuvette formée par une jupe périphérique de protection. Cet embout d'admission est destiné à coopérer avec un clapet d'éjection de la cartouche pour écarter le clapet de son siège et permettre ainsi le transfert de gaz de la cartouche dans le dispositif d'admission de l'appareil. Lors de l'opération de transfert, il faut assurer l'étanchéité autour du clapet de la cartouche et de l'embout d'admission de l'appareil. A cet effet, souvent, et notamment dans le cas de la cartouche décrite dans FR 2 771 796 , le clapet d'éjection de la cartouche se prolonge en un embout mâle qui coopère avec l'embout mâle d'admission de l'appareil à l'intérieur d'un raccord agencé de façon appropriée.Known admission devices, such as that described in FR 2,771,796 , comprise a male intake tip, inside a bowl formed by a protective peripheral skirt. This intake tip is intended to cooperate with a cartridge ejection valve to move the valve from its seat and thus allow the transfer of gas from the cartridge into the device of the device. During the transfer operation, it is necessary to seal around the valve of the cartridge and the nozzle of the device. For this purpose, often, and particularly in the case of the cartridge described in FR 2,771,796 , the cartridge ejection valve is extended into a spigot which cooperates with the male inlet of the apparatus inside a fitting suitably arranged.

Une telle disposition présente toutefois l'inconvénient que l'embout de clapet d'éjection de la cartouche fait saillie hors du bord d'une coupelle de protection, avec le risque qu'il soit cassé au cours de sa manutention, sans parler des contraintes de stockage et d'étanchéité.Such an arrangement, however, has the disadvantage that the ejection valve tip of the cartridge protrudes out of the edge of a protective cup, with the risk that it is broken during its handling, not to mention the constraints storage and sealing.

La présente invention vise à éliminer ces inconvénients.The present invention aims to eliminate these disadvantages.

A cet effet, elle concerne tout d'abord une cartouche de gaz comprimé destinée à alimenter en gaz un appareil de fixation à gaz comprimé, selon la revendication 1.For this purpose, it first relates to a compressed gas cartridge for supplying gas to a compressed gas fastening apparatus according to claim 1.

En toutes circonstances, le clapet d'éjection de la cartouche de l'invention ne fait donc plus saillie hors de la cuvette de protection et l'étanchéité est parfaite en position d'éjection.In all circumstances, the ejection valve of the cartridge of the invention therefore no longer protrudes out of the protective bowl and the seal is perfect in the ejection position.

Dans une première forme de réalisation de la cartouche, le clapet, en position de repos, fait saillie hors du joint d'étanchéité.In a first embodiment of the cartridge, the valve, in the rest position, protrudes out of the seal.

Dans ce cas, la surface d'appui du clapet est destinée à coopérer directement avec un embout mâle d'un dispositif d'admission de gaz de l'appareil pour repousser le clapet en position d'éjection dans laquelle le joint d'étanchéité s'étend de part et d'autre du plan de joint du clapet et de l'embout mâle du dispositif d'admission.In this case, the bearing surface of the valve is intended to cooperate directly with a male end of a gas intake device of the device to push the valve in the ejection position in which the seal s extends on both sides of the seal plane of the valve and the male end of the intake device.

Avantageusement, le joint d'étanchéité comporte un manchon externe et un cordon interne dans un épaulement annulaire d'une portion élargie du manchon.Advantageously, the seal comprises an outer sleeve and an inner bead in an annular shoulder of an enlarged portion of the sleeve.

L'invention concerne également un ensemble d'une cartouche de gaz comprimé pour alimenter en gaz un appareil de fixation et une coiffe d'adaptation selon la revendication 10.The invention also relates to an assembly of a compressed gas cartridge for supplying gas to a fixing apparatus and an adaptation cap according to claim 10.

Ni la cartouche, ni l'ensemble de l'invention peuvent être obtenus en considérant les documents US 4971 224 , considéré comme représentant l'art antérieur le plus proche, et GB 1 152 890 . et GB 1 152 890 .Neither the cartridge nor the whole of the invention can be obtained by considering the documents US 4971,224 , considered to represent the closest prior art, and GB 1 152 890 . and GB 1 152 890 .

En référence à la figure 4, une cartouche de gaz comprimé 1 se monte sur l'électrovanne 2 d'admission de gaz comprimé d'un appareil d'entrainement d'éléments de fixation du genre clou, par l'intermédiaire d'un raccord d'étanchéité 3.With reference to FIG. 4, a compressed gas cartridge 1 is mounted on the solenoid valve 2 for the compressed gas inlet of a fastener driving apparatus of the nail type, via a coupling sealing 3.

L'électrovanne d'admission 2 comporte un embout d'admission mâle 4 s'étendant axialement - le long de l'axe 8 - en saillie hors du fond 5 d'une cuvette 6, formée par une jupe annulaire 7 de réception d'un pied d'éjection 14 de la cartouche 1. L'extrémité 9 de l'embout d'admission 4 de l'électrovanne est en retrait par rapport au bord annulaire 10 de la jupe 7.The inlet solenoid valve 2 comprises a male inlet nozzle 4 extending axially - along the axis 8 - projecting from the bottom 5 of a bowl 6, formed by an annular skirt 7 for receiving the an ejection foot 14 of the cartridge 1. The end 9 of the intake nozzle 4 of the solenoid valve is set back with respect to the annular edge 10 of the skirt 7.

La cartouche de gaz comprimé 1 comporte une enveloppe cylindrique 11 se terminant par un épais bourrelet annulaire 12 formant cuvette 13 au centre de laquelle fait saillie le pied d'éjection 14. Le pied 14 ne fait pas saillie hors du plan du bord annulaire 15 du bourrelet 12. Dans l'exemple considéré, il l'affleure.The compressed gas cartridge 1 comprises a cylindrical casing 11 ending in a thick annular bead 12 forming a bowl 13 in the center of which projects the ejection foot 14. The foot 14 does not protrude out of the plane of the annular edge 15 of the bead 12. In the example, it is flush.

Un clapet d'éjection 16 est monté dans le pied d'éjection 14, coulissant dans un joint 20 en forme de manchon contre l'action d'un ressort de rappel 17. Le clapet 16 comporte, en saillie hors du joint 20, mais pas hors de la cuvette 13, une partie externe 18 prolongée par une partie interne 19 comportant un rebord annulaire d'étanchéité 21. Le ressort de rappel 17 est logé à l'intérieur du manchon de joint 20, autour de la partie interne de clapet 19, en appui contre le rebord annulaire d'étanchéité 21 de la partie de clapet 19, de diamètre sensiblement égal à celui de l'alésage central 22 du manchon 20 mais toutefois très légèrement inférieur, pour l'échappement du gaz comprimé entre la paroi de l'alésage 22 du manchon 20 et ce rebord 21. Au repos, le rebord 21 du clapet 16 est en appui contre un cordon annulaire d'étanchéité 23 logé dans un épaulement annulaire d'une portion élargie 24 du manchon d'étanchéité 20 du joint 3.An ejection valve 16 is mounted in the ejection foot 14, sliding in a sleeve-like seal 20 against the action of a return spring 17. The valve 16 has a projection out of the seal 20, but not out of the bowl 13, an outer portion 18 extended by an inner portion 19 having an annular sealing flange 21. The return spring 17 is housed inside the seal sleeve 20, around the inner portion of the valve 19, bearing against the annular sealing flange 21 of the valve portion 19, of diameter substantially equal to that of the central bore 22 of the sleeve 20 but still very slightly lower, for the exhaust compressed gas between the wall of the bore 22 of the sleeve 20 and the rim 21. At rest, the flange 21 of the valve 16 bears against an annular sealing bead 23 housed in an annular shoulder of an enlarged portion 24 of the sealing sleeve 20 of the gasket 3.

Le joint d'étanchéité 3 comporte donc un manchon 20 et un cordon 23 logés dans le pied 14 dont un bord annulaire 25 recouvre la portion élargie 24 du manchon et le cordon d'étanchéité 23. Le bord 25 du pied 14 affleure ici le plan du bord 15 du bourrelet 12. Le manchon d'étanchéité 20 est ainsi légèrement en retrait par rapport au plan du bord 15. La partie de clapet externe 18 présente, tournée vers l'extérieur, une surface 26 d'appui et de déplacement du clapet qui, en toutes circonstances, ne fait pas saillie hors du plan du bord 15. Ici, elle l'affleure. Par contre, dans la position de repos du clapet 16, sa partie externe 18, par sa portion adjacente à la surface d'appui 26, fait saillie hors du cordon d'étanchéité 23.The seal 3 thus comprises a sleeve 20 and a cord 23 housed in the foot 14, an annular edge 25 covers the enlarged portion 24 of the sleeve and the sealing bead 23. The edge 25 of the foot 14 is here flush with the plane The sealing sleeve 20 is thus slightly recessed with respect to the plane of the edge 15. The outer valve portion 18 has, facing outwards, a bearing surface 26 and valve which, in all circumstances, does not protrude out of the plane of the edge 15. Here it is flush. On the other hand, in the rest position of the valve 16, its outer portion 18, by its portion adjacent to the bearing surface 26, protrudes out of the sealing bead 23.

On notera que le diamètre de la partie de clapet externe 18 est sensiblement le même, très légèrement inférieur, que le diamètre de l'orifice de passage 27 du cordon d'étanchéité 23 et le même que le diamètre extérieur de l'embout d'admission 4.Note that the diameter of the outer valve portion 18 is substantially the same, very slightly less, than the diameter of the through hole 27 of the sealing bead 23 and the same as the outer diameter of the nozzle. admission 4.

En fonctionnement, la paroi latérale 28 de la partie de clapet externe 18 et la paroi latérale extérieure 29 de l'embout d'admission 4 sont successivement en contact avec la paroi de l'orifice de passage 27 du cordon d'étanchéité 23. Elles constituent des surfaces cylindriques d'étanchéité, d'axe 8.In operation, the side wall 28 of the outer valve portion 18 and the outer side wall 29 of the inlet nozzle 4 are successively in contact with the wall of the through hole 27 of the sealing bead 23. They constitute cylindrical sealing surfaces, with axis 8.

Plus précisément, et toujours en fonctionnement, l'extrémité 9 de l'embout 4 vient en appui contre la face 26 de la partie de clapet externe 18, disposée perpendiculairement à l'axe 8. Grâce à des moyens conventionnels non représentés, la partie de clapet externe 18, en fonctionnement, est repoussée en position d'éjection par l'embout d'admission 4 contre l'action du ressort de rappel 17, pour dégager le rebord du clapet annulaire 21 du cordon de joint 23 et laisser le gaz s'échapper de la cartouche 1 dans l'électrovanne 2 de l'appareil de fixation. Dans cette position d'éjection de gaz, la surface d'appui et de déplacement 26 du clapet 18, 19 est en retrait par rapport à la surface 30 tournée vers l'extérieur du cordon de joint 23, et même par rapport à sa surface 31 tournée vers l'intérieur.More specifically, and still in operation, the end 9 of the nozzle 4 abuts against the face 26 of the outer valve portion 18, disposed perpendicularly to the axis 8. With conventional means not shown, the part external valve 18, in operation, is pushed into the ejection position by the intake nozzle 4 against the action of the return spring 17, to disengage the flange of the annular valve 21 of the seal bead 23 and leave the gas to escape from the cartridge 1 into the solenoid valve 2 of the fixing device. In this gas ejection position, the bearing and displacement surface 26 of the valve 18, 19 is set back relative to the outwardly facing surface of the seal bead 23, and even with respect to its surface. 31 turned inward.

Dans la position d'éjection, le joint d'étanchéité 3, avec son manchon 20 et son cordon 23, s'étend de part et d'autre du plan de joint du clapet 18, 19 et de l'embout mâle d'admission 4, qui est le plan de la surface d'appui 26 de la partie de clapet externe 18.In the ejection position, the seal 3, with its sleeve 20 and its bead 23, extends on either side of the joint plane of the valve 18, 19 and the intake nozzle 4, which is the plane of the bearing surface 26 of the outer valve portion 18.

La deuxième forme de réalisation 1' de la cartouche, représentée sur les figures 5 à 8, se distingue ici de la première par deux caractéristiques seulement :

  • le pied d'éjection 14' est franchement en retrait par rapport au plan du bord annulaire 15 du bourrelet 12;
  • la partie de clapet externe 18', avec sa surface d'appui et de déplacement 26, en position de repos, est en retrait par rapport au plan de la surface 30 tournée vers l'extérieur du cordon d'étanchéité 23 du joint 3'.
The second embodiment 1 'of the cartridge, shown in Figures 5 to 8, differs here from the first by two characteristics only:
  • the ejection foot 14 'is positively recessed with respect to the plane of the annular edge 15 of the bead 12;
  • the outer valve portion 18 ', with its support and displacement surface 26, in the rest position, is recessed with respect to the plane of the outwardly facing surface of the sealing bead 23 of the gasket 3' .

Avec cette cartouche, on utilise un joint intermédiaire 40 monté dans une coiffe d'adaptation 50.With this cartridge, an intermediate seal 40 is used which is mounted in an adaptation cap 50.

Le joint intermédiaire 40 est un manchon, avec une première portion d'extrémité mâle 41, montée en appui contre la surface d'appui 26 du clapet 16 pour l'actionner et écarter son rebord d'étanchéité 21 du cordon d'étanchéité 23, et une deuxième portion d'extrémité femelle 42, destinée à recevoir l'embout mâle d'admission 4 de l'électrovanné 2. Le diamètre extérieur de l'extrémité d'actionnement 41 correspond à celui de l'embout mâle d'admission 4. L'alésage 43 de passage du gaz comprimé, s'étendant dans le joint intermédiaire 40, est étagé et sa section, dans la portion d'extrémité 42, est notablement plus grande qu'à l'autre extrémité 41 pour être d'un diamètre égal au diamètre extérieur de l'embout d'admission 4. En conséquence, le diamètre extérieur de la portion d'extrémité 42 est aussi élargi par rapport à celui de la portion d'extrémité 41. Pour améliorer l'étanchéité entre le joint intermédiaire 40 et l'embout d'admission 4, la paroi de l'alésage élargi 44 dans la portion d'extrémité 42 présente une lèvre annulaire d'étanchéité 45.The intermediate seal 40 is a sleeve, with a first male end portion 41, mounted in abutment against the bearing surface 26 of the valve 16 to actuate it and move its sealing flange 21 away from the sealing bead 23, and a second female end portion 42, intended to receive the male inlet end 4 of the electrovalve 2. The outer diameter of the actuating end 41 corresponds to that of the male inlet end 4 The bore 43 for passage of the compressed gas, extending into the intermediate seal 40, is stepped and its section in the end portion 42 is substantially larger than at the other end 41 to be of a diameter equal to the outer diameter of the intake nozzle 4. Accordingly, the outer diameter of the end portion 42 is also widened relative to that of the end portion 41. To improve the seal between the intermediate seal 40 and the intake nozzle 4, the wall of the enlarged bore 44 in the end portion 42 has an annular sealing lip 45.

La coiffe d'adaptation 50 a la forme d'une bague avec un alésage traversant étagé 51, 52, de section (51) d'un diamètre sensiblement égal au diamètre extérieur de la portion d'extrémité femelle élargie 42 du joint intermédiaire 40, dans une portion d'extrémité mâle 53 destinée à être reçue dans la cuvette 6 de l'électrovanne 2, et de section élargie (52) d'un diamètre sensiblement égal au diamètre extérieur du pied d'éjection 14', dans une deuxième portion d'extrémité femelle 54 destinée à recevoir ce pied d'éjection 14' de la cartouche 1'. L'alésage 51, 52 de la coiffe 50 s'étend sur une longueur sensiblement égale à celle du joint intermédiaire 40. A son extrémité de plus petite section 53, la coiffe 50 comporte un rebord annulaire 55 de retenue du joint intermédiaire 40. La paroi extérieure 56 de la coiffe 50 est également étagée, adaptée à l'alésage 51, 52 de réception du joint intermédiaire ainsi qu'à la jupe 7 de l'électrovanne 2 et elle se termine, à son extrémité élargie 54, par un bord annulaire 57 de diamètre extérieur égal au diamètre intérieur du bourrelet 12 de la cartouche 1' pour être reçu dans la cuvette 13 de la cartouche 1'.The adaptation cap 50 has the shape of a ring with a stepped through bore 51, 52, of section (51) of a diameter substantially equal to the outside diameter of the enlarged female end portion 42 of the intermediate seal 40, in a male end portion 53 intended to be received in the bowl 6 of the solenoid valve 2, and of enlarged section (52) of a diameter substantially equal to the outer diameter of the ejection foot 14 ', in a second female end portion 54 for receiving the ejection foot 14' of the cartridge 1 '. The bore 51, 52 of the cap 50 extends over a length substantially equal to that of the intermediate seal 40. At its end of smaller section 53, the cap 50 has an annular rim 55 for retaining the intermediate seal 40. outer wall 56 of the cap 50 is also stepped, adapted to the bore 51, 52 for receiving the intermediate seal and the skirt 7 of the solenoid valve 2 and ends, at its widened end 54, by an edge annular 57 of outer diameter equal to the inner diameter of the bead 12 of the cartridge 1 'to be received in the bowl 13 of the cartridge 1'.

Ce n'est donc qu'en position de fonctionnement que le joint intermédiaire 40 et la coiffe d'adaptation 50 font saillie hors de la cuvette 13 de la cartouche 1'.It is therefore only in the operating position that the intermediate seal 40 and the adapter cap 50 project out of the bowl 13 of the cartridge 1 '.

En fonctionnement, pour repousser le clapet d'éjection 16 de la cartouche 1' de sa position de repos (figures 5, 6) à sa position d'éjection (figure 7), l'extrémité mâle 41 du joint intermédiaire 40 étant en appui contre la surface 26 du clapet 16 grâce à la coiffe d'adaptation 50, immobilisée dans la cuvette 13 de la cartouche 1', le joint intermédiaire 40, repoussé par l'embout d'admission 4, repousse la portion de clapet 18' contre l'action du ressort 17, pour dégager le rebord de clapet annulaire 21 du cordon de joint 23 et laisser le gaz s'échapper de la cartouche 1' dans l'électrovanne 2 de l'appareil de fixation. Alors, le joint intermédiaire est aussi dégagé du rebord 55 de la coiffe 50. Dans cette position d'éjection de gaz, la surface d'appui et de déplacement 26 du clapet 18', 16, est en retrait par rapport à la surface 31 du cordon 23, tournée vers l'intérieur.In operation, to push the ejection valve 16 of the cartridge 1 'from its rest position (FIGS. 5, 6) to its ejection position (FIG. 7), the male end 41 of the intermediate seal 40 being in abutment against the surface 26 of the valve 16 thanks to the adapter cap 50, immobilized in the bowl 13 of the cartridge 1 ', the intermediate seal 40, pushed back by the intake nozzle 4, pushes the valve portion 18' against the action of the spring 17, to disengage the annular valve flange 21 of the seal bead 23 and allow gas to escape from the cartridge 1 'in the solenoid valve 2 of the fastener. Then, the intermediate seal is also disengaged from the rim 55 of the cap 50. In this gas ejection position, the bearing and displacement surface 26 of the valve 18 ', 16 is set back relative to the surface 31. cord 23, turned inward.
